Climbing the Landfill

Garbage on the way UP. These are the GPK cards with genuine upward momentum right now — ranked purely from real recorded sales (never estimates): net 30-day and 90-day price moves plus how fast copies are actually changing hands. 628 cards had enough sales to be measured; these 9 are climbing hardest. Includes sales reported through 2026-08-24 (PSA reports sales ~2 days behind); rankings refresh hourly.

Climbing ranks each card's own window-median move (30d vs prior 60d, 90d vs prior 90d; both windows need 3+ sales) — a window-median engine, distinct from the repeat-sales trend tiles above.

How this board works

Every number here comes from real recorded sales of each exact card and grade — never from our value estimates and never from modeled prices. A card must have at least 6 recorded sales in the past year to qualify, so thinly-traded cards can't fake a trend with one lucky auction. The 30-day trend compares the median sale price of the last 30 days against the median of the 60 days before that; the 90-day trend compares the last 90 days against the prior 90. Both are net window-vs-window moves, so a card that just bounces up and down doesn't register as a climber. Velocity compares sales volume in the last 30 days to the card's own average 30-day pace over the preceding 90 days — cards selling faster than their norm get a boost, because rising prices on rising volume is the strongest kind of climb. The final rank blends the two price trends (30-day weighted heavier) plus the volume bonus. Cards whose last 30 days contradict the climb are dropped.

Momentum is a description of what just happened, not a promise of what happens next. Past climbs don't guarantee future climbs. This is automated market analysis for entertainment and research — not financial advice.
